I would stay away from "electical superchargers". It ends up being a quick buck for them and a slap in the face for you when nothing happens. On a side note, I witnessed something unbelievable back in October at our car clubs dyno day. A Ford Ranger 4 banger put down 23whp over stock with the aid of a Stihl leaf blower. Now that was some serious F/I. I'll see if I can find some pics.
